A problem while validating the state of active directory

23 Nov

In some cases, though, you might see one of these errors during an Adprep operation: The overall Server 2008 or Server 2008 R2 upgrade process is described in the Microsoft article "Upgrade Domain Controllers: Microsoft Support Quick Start for Adding Windows Server 2008 or Windows Server 2008 R2 Domain Controllers to Existing Domains." After Adprep completes successfully, you can install the first DC that runs Server 2008 or Server 2008 R2 into your existing AD.

If you choose to install the DNS server role during the DC installation, you might see this warning, which Figure 1 shows: "A delegation for this DNS server cannot be created because the authoritative parent zone cannot be found or it does not run Windows DNS server.

In “Troubleshooting DNS Problems in an Exchange Environment” ( ID/95748/95748.html), I explained that the health of your DNS operations is crucial to the health of your Exchange environment.

But if you're a less-experienced administrator who needs to replace DCs that run Windows Server 2003 with those that run Server 2008 R2, this article will shed some light on these issues and can help you avoid problems.To get the latest version of Exchange 2013, download and install Microsoft Exchange Server 2013 Cumulative Update 14. Of course, if you’re reading this, you already know that. I walked into installation of Cumulative Update 14 in an effort to help resolve problems with an installation of an On Premises Exchange Server 2013 that had suddenly, and recently, begin having problems with OWA. That said, the problems I encountered during this installation, which was a jump from Exchange Server 2013 Cumulative Update 7 (which had completed without a hitch) on a Hyper-V Guest on Windows Server 2012, could have been entirely addressed by better error handling when Microsoft prepped the CU – which would have saved my customer – and a lot of other people’s, too – a ton of money, and me a few hours of sleep. Because each CU is a full installation of Exchange and includes updates and changes from all previous CU’s, you don’t need to install any previous CU’s or service packs first. Many thanks to those in the forum and blogospheres for helping me solve this problem. Still, administrators often have questions: The Microsoft article " Running Adprep.exe" explains all that and more: the utility's general purpose, the process for running the necessary commands, and how to validate the utility's success.(If you want to review the exact changes that Adprep operations make to prepare an existing AD, see the Microsoft articles " Windows Server 2008: Appendix of Changes to to Support AD DS" and " Windows Server 2008 R2: Appendix of Changes to to Support AD DS." ) When running Adprep, plan for these important factors: If you can prepare for these potential issues and follow the process that the previously mentioned articles describe, you should have no trouble.
